Siemens Building Technology SAS61.33U Actuator
The Siemens Building Technology SAS61.33U Actuator is a precision-engineered Acvatix electromotoric spring return valve actuator designed for the proportional control of Powermite 599 Series terminal unit valves. Operating on 24V AC/DC power, this unit accepts a 0-10 VDC or 4-20 mA control signal to maintain precise positioning in HVAC systems. In the event of power loss, the integrated mechanical spring return function ensures a fail-safe move to the normal position in under 14 seconds, protecting downstream components. This 400N force actuator features a 7/32-inch (5.5 mm) stroke and high backward compatibility, frequently serving as a direct replacement for legacy SQS65.5U models. Built for the field, it includes a manual override knob with automatic reset, an LED status indicator, and power-dependent valve seat detection for simplified commissioning. With an IP54 protection rating and UL listing for plenum installations, it provides reliable performance in liquid and low-pressure steam applications across commercial environments.
- Fail-Safe Protection: Mechanical spring return ensures a fail-safe state during power interruptions.
- Universal Compatibility: Optimized for Siemens Powermite 599 Series and older Landis & Gyr valves with the ASK30 adapter.
- Streamlined Installation: Features auto-calibration and valve seat detection to reduce field setup time.
- Precise Control: Modulating 0-10 VDC positioning provides stable performance for heating and ventilation plants.
- Durable Design: Robust construction with 400 Newton positioning force and maintenance-free reversible motor.
Common Questions
What is the primary difference between the SAS61.03U and the SAS61.33U?
The SAS61.33U includes a mechanical spring return function for fail-safe operation, whereas the SAS61.03U is a non-spring return (fail-in-place) version.
Can this actuator be mounted in any orientation?
Installation is flexible from upright to horizontal, though it must not be mounted with the actuator positioned lower than the valve body.
Which valve series is the SAS61.33U compatible with?
It is specifically designed for 5.5 mm stroke valves, including Siemens MT Series types V..G44, VVG55, and VVG549.
